Ayuda Digital - Docker Generic Platform

Platform - GitOps

Overview

Set of pieces able to act as a Docker Training Lab. Key points:

• Docker Powered
• Fully automated
• Infrastructure as Code provisioning
• DevOps / GitOps (2) mindset
• Compliant with The Devops Hispano Challenge (1)

Objective

Learn to work on a platform composed of different components (services and products) with a kind of microservice architecture. Each piece of the platform can be developed, implemented and operated separately.

Requirements

• Docker installed
• Ayuda Digital - Devcontrol Tool installed (3)

Components

Products

Developed by the Business Teams. Defined as the things that the customers or the end users can use.

• Web Application Server GP Webapp.
• Statics Server GP Statics.

Services

Developed by the Platform Teams. Used to develop, build and operate the products.

• HAProxy from GP HAProxy.
• Jenkins from GP Jenkins.
• Mail from GP Mail.
• Statics with Nginx from GP Nginx.
• Artifacts with Sonatype Nexus from GP Nexus.
• Webapp with PHP from GP PHP.
• Passbolt fromn Official Passbolt docker-compose recipie.
• Sonar from GP Sonarqube.

Operation

1. Install assets with devcontrol assets-install
2. Configure the pieces (products and services); review each piece documentation of how to setup.
3. Start all components with devcontrol platform start
4. Check the health of the products and services:
   1. Webapp product: http://localhost:8001
   2. Statics product: http://localhost:8002
   3. Jenkins service: http://localhost:4001
   4. Sonar service: http://localhost:4002
   5. Nexus service: http://localhost:4003
   6. Passbolt Service: http://localhost:4004
5. Make backups of the platform with sudo devcontrol backup. Note the use of sudo for the backups.
6. Stop the platform with devcontrol platform stop
7. Destroy the platform with devcontrol platform destroy

Backups

Execute a backup of the static data, configurations and databases with sudo devcontrol backup.

Find three directories under /var/backups/docker directory with the configurations ad data for:

• products: all products
• services: all services
• volumes: the docker volumes of products and services

There are two sets of backups, with filenames beginning with "latest_" for the most recent ones, and "previous_" prefix for the oldest. The backup script will rotate the files from latest_ to previous_ with every execution.

You can put a crontab file under /etc/cron.d/gp_backup to set a daily backup task.

# cat /etc/cron.d/gp_backup
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user	command
00 04	* * *	root    (cd /home/master/platform; devcontrol backup > /var/log/gp_backup.log 2>&1)
